 Dear DPDK experts.
 
Thank you very much for your best great efforts and precious answers.
 
As you suggested, I reinstalled newer version of Fedora 22.
 
I succeeded to communicate test-pmd in Fedora 22 (linux kernel version 4.2.3-200.fc22.x86_64, DPDK 2.1.0).
 
The steps are as follows.
 
 
sudo yum install gcc
sudo yum install kernel-devel
sudo yum install libpcap-devel 
 
And then I patched the source codes as in  http://dpdk.org/dev/patchwork/patch/6800/   Patchwork [dpdk-dev] kni: fix igb build with kernel 4.2.
 
And then, I followed the quick start instructions from http://dpdk.org/doc/quick-start .
 
The test-pmd example seems to work.
 
Thank you very much.
 
 
 
I have another problem.
 
As in the following test-pmd log scripts, most of received packets are RX-error.
 
The same errors are occurred in the Ubuntu OS computer (Ubuntu 14.04.1 LTS, kernel version : 3.13.0-34-generic, DPDK 2.1.0).  
 
If you have any advices or answers for the above problem, I will really appreciate.
 
Thank you very much.
 
Sincerely Yours,
 
Ick-Sung Choi.

Hi,



This may be a known issue. See:





http://dpdk.org/doc/guides/rel_notes/known_issues.html#devices-bound-to-igb-uio-with-vt-d-enabled-do-not-work-on-linux-kernel-3-15-3-17





"Devices bound to igb_uio with VT-d enabled do not work on Linux kernel 3.15-3.17



Description:

    When VT-d is enabled (iommu=pt intel_iommu=on), devices are 1:1 mapped. In the Linux kernel unbinding devices from drivers removes that mapping which result in IOMMU errors. Introduced in Linux kernel 3.15 commit, solved in Linux kernel 3.18 commit."
